To all whom 2'15 may concern.

Be it known that I, EMIEL PAHL, a citi- Zen of the United States,residing at Sister Bay, in the county of Door and State of lVisconsin,have invented certain new and useful Improvements in Platforms forEngines, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to agricultural machinery and has specialreference to a platform adapted to be attached to a harvester or thelike for the purpose of carrying an engine to drive the harvester.

The principal object of the invention is to provide a form of platformwhich can be attached to any design of harvester.

A second object of the invention is to provide a platform adapted forconnection to a harvester and which is adjustable to various heights.

Vith the above and other objects in view, this invention consists ingeneral of certain novel constructions, combinations and arrangements ofparts, as will be hereinafter fully described, illustrated in theaccompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and Figure 1 is a plan view of a portion ofa harvester with the platform and engine applied thereto. Fig. 2 is aside elevation of the platform as applied. Fig. 3 is a detailperspective of the manner in which certain bars are attached to the reartransverse frame bar of the harvester. Fig. d is a detail sectionthrough a certain clutch used in connection with this platform. Fig. 5is a detail side view of a portion of the belt tightener.

It is to be noted that the device in question is intended to beconnected at one side of the harvester and in the present instance thesame is shown as connected to the left side thereof, the cutter bladesbeing located to the right.

It is further to be understood that only a portion of the harvester isdisclosed herewith since the harvester itself forms no specific part ofthe invention.

All harvesters are provided with a rear frame member 10 and upon thisrear frame member there is attached pairs of spaced ears 12. Secured tothe cars 12 and eX- tending rearwardly therefrom are longi-Specification of Letters Patent.

tudinal frame members 13, which have their forward ends pivoted betweenthe pairs of cars. To the rear of these frame members 13 are attachedlongitudinal members 14 whereto may be bolted the base of an engine 15of any desirable type, the engine being preferably provided with adriving shaft 16. Between the pairs of ears 12 are pivoted thehorizontally diagonal brace members 17, the other ends of these menrbers being connected to the members 14 in any suitable manner.

Extending upward from the rear ends of the members it are uprights 18which are providedwith a series of spaced open ings 19 for the receptionof adjusting bolts The upper ends of the members 18 are braced to themembers 13 by braces 21 and attached to the members 18 by the bolts 20is a substantially U-shaped yoke his yoke is provided at the center ofits bight with a suitable opening for the reception of a bolt 23 and tothis bolt is pivoted a pair of members 2 1, one of the members lyingabove and the other below the yoke 22. These members are held apart bysuitable spacers 25, and depending from the members 24: are standards 28which serve o support journal boxes 27 wherethrough passes a shaft 28carrying the wheels 29.

To the members 18 there is secured a pair of clips 30, each of which hasa series of openings 31 made therethrough. In a selected opening 81 ofeach clip is held the hook end 32 of a spring 33 provided on its otherend with an eye which engages an eye 35 on the bolt 23. By this meansthe rear truck is yieldably connected so as to rise and fall withincertain limits and accommodate itself to the inequalities of the ground.

Mounted upon the shaft 16 is a clutch member 36 which is keyed orotherwise fixedly secured to the fly wheel 37 of the en gine and thisclutch member is adapted to be engaged by a clutch member 38 preferablyformed integral with the sprocket gear 39 carrying a sprocket chain 40which connects the sprocket wheel 39 with a similar gear 41 carried onthe main drive shaft 12 with which harvesters are commonly equipped.

Through suit-able gearing, indicated in general at 4L3, this drive shaftis adapted to drive the cutter mechanism of the harvester. Upon theshaft d2 may also be mounted, 1f

desired, a sprocket 44: which is connected by a chain 45 with a sprocketwheel fixed upon the axle as which supports the ground wheel 47 of theharvester.

In order to show the clutch members into and out of engagement there isprovided a transverse frame member 47 whereto is pivoted a lever aswhich is provided with a forked end. 49. This forked end 49 engagesaround the hub of the clutch member 38 between the same and the sprocketgear 39 so that as the lever is moved in one direction or the other themembers 36 and 38 will be engaged or disengaged as the case may be. Thislever 48 is provided with a handle 50 which extends upward to aconvenient position adjacent the drivers seat 51. The lever 48 isfurthermore provided with the usual latch 52 and on the frame is mounteda quadrant 58 which said latch engages.

In order to keep the belt tight there is at tached to the frame of theharvester an eye 54; having an arm 55 pivoted thereto and pivoted to theouter end of this arm is a pair ofarms 56 each carrying a belt tightener57, said belt tightening rollers bearing on the innerside of the belt/40and being held firmly pressed thereagainst by means of a suitable coilspring 58.

The harvester when used with this device is preferably provided withmeans for attaching a draft pole 52 so that if desired it the chain asmay be removed and draft animals used to vdraw the harvester from placeto place While the engine may be used to run the cutting mechanism.

members having their forward ends sinui larly attached and their rearends fixedly connected to the longitudinal members, uprights at the rearends of said longitudinal members provided with means for pivotallyattaching a yoke adjustably thereto, a yoke attached to said uprights bysaid means, a supplementary frame, a Vertically dispose? pivotconnecting the yoke and the supplementaryframe, standards extendingbelow the supplementary frame, ground wheels carried by said standards,and means to prevent upward movement of the yoke at its rear end.

Quin a device of the kind described, a 1 platform comprising a pair oflonglt-udlnal. 1

frame members having their forward ends adapted for pivotal connectionto a harvester, a pair of laterally diverging brace members having theirforward ends sinnlarly attached and their rear ends fixedly it connectedto the longitudinal members, up-

rights at the rear ends of said longitudinal,

members provided with means for pivotally attaching a yoke adjustablythereto, a yoke.
